Mizzou Bio 1500 Exam 3 Bush Questions And
Answers |Latest 2025 | Guaranteed Pass.
Describe an effective experimental design to determine whether an environmental variable
imposes selection on a trait. - Answer✔-need multiple generations
-need a control group
-need different levels of oxygen
-need a small organism that reproduces quickly
-need a confined environment
How does natural selection cause dramatic changes in phenotypes? - Answer✔Different levels
of oxygen can change body size, certain phenotype survives, reproduces over generations to
become popular in populations. Higher oxygen levels means animals can grow larger and still
maintain the supply of oxygen to their muscles.
What are the four categories of Organic Molecules? - Answer✔1. Carbohydrates
2. Lipids
3. Proteins
4. Nucleic Acids
What is an organic molecule? - Answer✔A molecule that contains a carbon.
What are some examples of carbohydrates? - Answer✔Glucose, starch, glycogen, cellulose,
chitin.
What are some examples of lipids? - Answer✔Fats, oils, waxes, olive oil, bees wax, bacon fat.
When a fat is 'saturated', what is it saturated with? - Answer✔H2
What are the building blocks of proteins? - Answer✔amino acids
What are the building blocks of nucleic acids? - Answer✔nucleotides

What are the building blocks of carbohydrates? - Answer✔simple sugars (monosaccharides)
What are the building blocks of lipids? - Answer✔fatty acids and glycerol
What is cellulose? - Answer✔Polysaccharide consisting of glucose monomers. The main
constituent of a plant cell wall and of vegetable fibers
Which would have the most cellulose?
-steak
-bowl of ice cream
-mushroom omelet
-serving of broccoli - Answer✔serving of broccoli
Phospholipids are important components of which cellular structure?
-membranes
-ribosomes
-mitochondria
-chromosomes - Answer✔membranes
What is the outcome of dehydration? - Answer✔Two molecules form a chemical bond.
What is the outcome of hydrolysis? - Answer✔A starch is broken into simple molecules.
What is dehydration synthesis? - Answer✔Water is given off when two monosaccharides are
joined together. Water is removed.
What is hydrolysis? - Answer✔The separation of two macromolecules by adding water.
Why are cells small? - Answer✔As the cell increases in size, materials diffusing in the cell will
not be able to reach the core as efficiently as in a small cell. The higher the SA:V ratio, the less
efficient a cell is. The bigger cell will have slower cellular signaling response.
What are the similarities between Prokaryotes and Eukaryotes? - Answer✔-chromosomes
-DNA is genetic material
-ribosomes
-cytoplasm
-plasma membrane
-vacuoles
